Subject: Re: STRUCT: substructuring rules
Author: Sharma Shashikant

Hi David,
You maybe right. I used to take submodeling as super-element modeling, and
substructuring as second model of zone of interest with refined mesh and BCs
interpolated on interface. Any ideas there now?

thanks,

Shashikant Sharma,

Do you mean SUBMODELING (and not SUBSTRUCTURING) ?
